A very good factually white theme (Blender Light is Not light enough for me) that simultaneously is easy on the eyes. The only gimmick is that text on the status bar is barely visible against the background. You can mitigate that by going into Preferences>Themes>User Interface>State and changing the first four to be of a less dark, and possibly less saturated colour
This Softimage XSI theme for Blender is a total throwback—slate-gray, pastel pops, and that no-nonsense layout hit all the right notes. It’s like dusting off an old rig and firing up a project from the glory days. Smooth, intuitive, and cuts the fluff. It’s a badass nod to the past that works like a charm. 5 stars—nails it. If you're a fan of XSI, this theme will feel like home.
Clean and easy on the eyes
Flashback, Sigh! This is a wonderful thank you.
This version of the theme for v5 is broken in several areas, especially in the asset shelf. I uploaded a tweaked version for download here: https://projects.blender.org/extensions/theme_xsi/issues/3 Hopefully the mods can switch them out, so the theme works properly again :)
